How good is the audio and video quality of a group video conferencing?
The quality of any video conference, stream, broadcast or virtually any video transmission is primarily a function of the bandwidth available for transmission and to some degree the quality of the compression and decompression of the images, if compressed as they are in video conferencing. Generally, the higher the bandwidth, the better the video. A typical corporate group video conferencing installation today is utilizing 384k (k is short for Kilobits) of bandwidth. Because almost all systems are designed to be compatible, they are all made to meet the ITU standards which for ISDN video is called H.320 and for IP video is H.323. This provides very near TV quality video and audio in a meeting environment and is generally chosen by most companies due to the right mix of quality and cost.
